To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.
1. 29.68 / 4 = 7.42
So $7.42 is the unit price.
2. 625 / 6 = 104 (rounded to the nearest whole number)
So Jess can type 104 words per minute.
Answer:
(a,b)----->(2,8)let
we have
m(x-a)=(y-a)where m=slope
4(x-2)=(y-8)
4x-8=y-8
4x-y=8-8
4x=y is required equation.
Answer:
A) 1.5
B) x^2-23x+42 = (x-2)(x-21)
C) x=2, x=21
Step-by-step explanation:
a) 15 -2x / 3 = 4
15-2x = 12 (Times by three on both sides)
-2x = -3
x = -3/-2 = 3/2 = 1.5
b) x^2-23x+42
x^2-23x+42 = (x-2)(x-21)
c) x^2 -23x +42 = 0
x=2, x=21
(x-2) = 0 ⇒ x = 2
(x-21) = 0 ⇒ x = 21
2.75%= convert it to a decimal
.0275
Now, multiply that by 20.
20*.0275= 0.55
0.55 is 2.75% of 20.
I hope this helps!
